Salesforce connected-app user provisioning can be combined with internal approval so downstream accounts are created only after the right business authorization is complete. The connected app must have user provisioning enabled, and the target application must be represented as a connected app in Salesforce. To control timing, the approval process should be associated with the provisioning request object that participates in the provisioning lifecycle rather than with the generic User object. That allows the organization to hold or approve the provisioning action itself. This pattern is useful when HR or compliance wants a formal checkpoint before external accounts are created. The architecture separates identity eligibility from final outbound provisioning execution. This is why options B, C, D work together as the correct solution.
